Overview
The 74LVC273D is an octal positive-edge triggered D-type flip-flop produced by Nexperia USA Inc. This device is part of the 74LVC family, known for its low voltage CMOS logic. It features clock (CP) and master reset (MR) inputs, making it versatile for various digital circuit applications. The outputs Qn assume the state of their corresponding D inputs during the LOW-to-HIGH clock transition, and a LOW on the MR input forces the outputs LOW, independent of the clock and data inputs. This component is suitable for use in mixed 3.3 V and 5 V environments due to its input voltage tolerance and compatibility with TTL levels.
